★★★

Argylle opens bad. Seriously bad. Dead-on-arrival bad. Offered up is all-star – Dua Lipa! John Cena! Superman! – Grecian espionage but one woefully written, dismally acted and laden with risible special effects. But, wait! What’s this? A story within a story? Now we’re talking. There’s hope yet. Hold on to it. Sure enough, the film that follows improves not merely on the first five minutes but much of its director’s recent work. Matthew Vaughn’s, until now, unstoppable descent into distaste finally desists for Argylle, an overlong but mercifully entertaining romp.
